plot3(x, y, z)
plot3(x, y, z, pspec)
plot3(x, y, z, pspec, x1, y1, z1, pspec1....)
Inputs  
x 
The vector of xcordinates of the curve to be plotted. 
y 
The vector of ycordinates of the curve to be plotted. 
z 
The vector of zcordinates of the curve to be plotted. 
pspec 
The string containing the specifications of line style and the color. 
{x1, y1, z1, psec1} 
The vector of x , y , and z coordinates of the second curve to be plotted, with pspec1 being
the specifications for line style and color for the second plot.

x, y, z
together with the option specification
pspec
may be specified for multiple curves.
pspec
should be defined according to the
description in the function plot.
